How to handle anchor hash linking in AngularJS

The Solution to How to handle anchor hash linking in AngularJS is


You're looking for $anchorScroll().

Here's the (crappy) documentation.

And here's the source.

Basically you just inject it and call it in your controller, and it will scroll you to any element with the id found in $location.hash()

app.controller('TestCtrl', function($scope, $location, $anchorScroll) {
   $scope.scrollTo = function(id) {
      $location.hash(id);
      $anchorScroll();
   }
});

<a ng-click="scrollTo('foo')">Foo</a>

<div id="foo">Here you are</div>

Here is a plunker to demonstrate

EDIT: to use this with routing

Set up your angular routing as usual, then just add the following code.

app.run(function($rootScope, $location, $anchorScroll, $routeParams) {
  //when the route is changed scroll to the proper element.
  $rootScope.$on('$routeChangeSuccess', function(newRoute, oldRoute) {
    $location.hash($routeParams.scrollTo);
    $anchorScroll();  
  });
});

and your link would look like this:

<a href="#/test?scrollTo=foo">Test/Foo</a>

Here is a Plunker demonstrating scrolling with routing and $anchorScroll

And even simpler:

app.run(function($rootScope, $location, $anchorScroll) {
  //when the route is changed scroll to the proper element.
  $rootScope.$on('$routeChangeSuccess', function(newRoute, oldRoute) {
    if($location.hash()) $anchorScroll();  
  });
});

and your link would look like this:

<a href="#/test#foo">Test/Foo</a>
